Abstract
Methods and apparatuses for channel state information (CSI) reporting in a wireless communication system. A method for operating a user equipment (UE) includes receiving a configuration about a CSI report, the configuration including a value of N4 and a codebookType. The method further includes, based on the configuration: determining, based on a condition, whether the CSI report includes an indicator indicating Q time domain (TD)/Doppler domain (DD) basis vectors and when the condition is met, determining the Q TD/DD basis vectors, each of length N4. The method further includes transmitting the CSI report including the indicator indicating the Q TD/DD basis vectors when the condition is met.
Claims12
A user equipment (UE) comprising:
- a processor;
- and
- a transceiver operably coupled to the processor, the transceiver configured to:
- receive, from a base station, first information configuring a codebook for a channel state information (CSI) report, wherein the first information includes second information on a length of a doppler-domain (DD) basis vector (N4);
- and
- transmit, to the base station, the CSI report,
- wherein, when the length of the DD basis vector (N4) is one of 2, 4 or 8, the CSI report includes information on the DD basis vector (N4) and a number of DD basis vectors (Q) for the CSI report is 2.
A base station (BS) comprising:
- a transceiver configured to:
- transmit, to a user equipment (UE), first information configuring a codebook for a channel state information (CSI) report, wherein the first information includes second information on a length of a doppler-domain (DD) basis vector (N4);
- and
- receive, from the UE, the CSI report,
- wherein, when the length of the DD basis vector (N4) is one of 2, 4 or 8, the CSI report includes information on the DD basis vector (N4) and a number of DD basis vectors (Q) for the CSI report is 2.
A method for operating a user equipment (UE), the method comprising:
- receiving, from a base station, first information configuring a codebook for a channel state information (CSI) report, wherein the first information includes second information on a length of a doppler-domain (DD) basis vector (N4);
- and
- transmitting, to the base station, the CSI report,
- wherein, when the length of the DD basis vector (N4) is one of 2, 4 or 8, the CSI report includes information on the DD basis vector (N4) and a number of DD basis vectors (Q) for the CSI report is 2.
